18,000 kWh for a somewhat modern building is quite a statement. In the 1970s construction, we had 21 m² (approximately 226 sq ft) with 22,000 kWh including a heated conservatory (new gas boiler, radiators).

We have already discussed the topic; Bookstars’ house and location remain a mystery. It’s always cold outside, no solar gains, and the house consumes heat like a black hole.

Well, that shows what insulation mania brings, namely nothing. Others are not much lower either. But that’s just how it is 🙂

Same here, around 11,000 including hot water.

Better to have “insulation craze” than escape from reality.

Okay, I’m about one-third above that. Where does it come from? I have no idea. Everything is standardized, stone and insulation materials. It can only be due to the location and temperatures, etc.…

Hemp plantation inside the house? Then you always need 28°C (82°F). 😉
